If you have a light weight MacBook or MacBook Air that you can take with you. You do not want to drag along a heavy manual. There are times when you can't remember how to enter a special character, or a needed key command (Chapter 8; Keyboard Commands and Special Characters). There are times when you experience a problem (Chapter 4; Trouble Shooting Mac OS X). There are times when you can"t remember a password (Chapter 7: Managing Passwords in Lion). There are times when you need a small light weight pocket guide (Mac OS X Lion Pocket Guide).

Mac OS X Lion Pocket Guide begins with a good quick introduction to what is new in Lion, and how to install it, and how to use it. It also includes a chapter on System Preferences. In just a small page and a half it covers the essentials of Mission Control "you're going to love it." Did you know that the symbol on the Command key is the "Place of Interest Symbol?"
